Windows: We've discussed lots of great apps that remind you to take periodic breaks to rest your eyes and save your sanity, but most of them have been for the Mac. Windows users can get in on the fun with EyeLeo, a completely free download that doesn't just remind you when it's time to take a break, it also dims your screen so you actually get up from the computer and go do something else.

EyeLeo works much like Coffee Break for the Mac. The app reminds you to take short eyestrain breaks every few minutes, and longer, get-up-from-the-computer breaks every hour or so.

You can also set how long that break is.

EyeLeo is probably the best Windows break reminder we've seen since WorkRave, which we know is a favorite for many of you. EyeLeo was built by engineers who tried WorkRave and wanted something a bit more customizable, but we'll leave it to you to decide which one's the best for the way you work. EyeLeo is free, and available now.
